← ScienceWhich outcome occurs when a microstrip patch antenna's length reaches λ/2?
A)Peak gain develops through resonance✓
B)Input impedance becomes purely reactive
C)Bandwidth diminishes dramatically at cutoff
D)Polarization shifts into circular orientation
💡 Explanation
Peak gain results because standing waves constructively interfere during resonant antenna operation, which relies on the Resonance mechanism providing optimal radiation efficiency with high gain matching. Therefore, the antenna efficiently emits, rather than behaving reactively thanks to correct dimensioning.
